Sitting at a Desk All Day Is Doing Something to Your Spine. Here Is What We See in Clinic.

You sit down at 9am with every intention of taking breaks.

Then you answer one email, jump into a meeting, finish something that was due yesterday and suddenly it's 1:30pm and you're wondering if you've moved at all.

By the end of the day, your lower back feels stiff. Your shoulders have slowly crept toward your ears. You stand up and need a second before your body feels ready to move again.

If this sounds familiar, you're definitely not the only one.

But before you blame your office chair or start worrying that eight hours at a desk is ruining your spine, there's something important to know:

Sitting isn't automatically bad for your back.

The research is actually much more interesting than that.

Is sitting all day actually causing your back pain?

Not necessarily.

For years, we've heard some version of: Sitting is terrible for your back.

But research hasn't shown that sitting alone directly causes lower back pain.

A large review looking at spinal posture and physical exposures found mixed evidence around sitting, bending, posture, and lower back pain. The researchers couldn't establish that one particular posture or physical exposure was causing the problem.

More recently, though, researchers have started looking at office work in a slightly different way.

A 2025 review examined 22 studies involving more than 7,800 office workers. The interesting finding wasn't simply "sitting causes back pain."

The strongest relationship showed up around sitting behaviour.

Things like spending longer periods sitting without changing position, taking fewer breaks, and having a more static workday were more consistently associated with lower back pain.

So perhaps the conversation shouldn't be:

"Am I sitting wrong?"

It might be:

"Have I moved at all in the last three hours?"

Your best posture might just be your next posture

We've all seen the perfect desk setup.

Feet flat. Knees at 90 degrees. Back straight. Shoulders down. Monitor exactly at eye level.

And yes, having a comfortable workstation can absolutely help.

But trying to hold one "perfect" position all day isn't realistic.

Think about what happens even when you're sitting in the world's most ergonomic chair.

At 9am, you're upright.

By 10:30am, you've crossed one leg.

At noon, you're leaning toward the screen.

At 2pm, you're sitting sideways while talking on the phone.

By 4:30pm, who even knows what position you're in anymore.

That's normal.

Your body isn't designed to stay perfectly still.

And research doesn't give us good evidence that there is one universally correct spinal posture that everyone needs to maintain to avoid lower back pain.

So rather than constantly correcting yourself every time you slouch, think about variety.

Sit back for a while. Lean forward when you need to. Stand up. Walk to refill your water. Take the call standing if that feels good.

The goal isn't perfect posture.

It's giving your body options.

Why can you feel so stiff when you finally stand up?

You know that feeling when you've been sitting through a long meeting, stand up, and for the first few steps your body seems to need a minute?

That doesn't automatically mean something has gone wrong with your spine.

Staying in one position for a long time can simply feel uncomfortable.

Your muscles and joints have been doing the same thing for a while, and then you're suddenly asking them to do something different.

Sometimes a little movement is all your body was asking for.

Research on workplace breaks gives us some support for this. A systematic review found that active breaks involving a change in posture may help reduce pain and discomfort in office workers, without evidence that taking those breaks harmed productivity.

So you don't necessarily need a 30-minute mobility routine between meetings.

Sometimes standing up, walking around for a few minutes, or simply changing position is a reasonable place to start.

What about standing desks?

A standing desk can be useful.

But it isn't magic.

If you replace eight hours of sitting still with eight hours of standing still, we've kind of missed the point.

Research on sit-stand workstations suggests they may reduce lower back discomfort for some workers, but the evidence doesn't tell us that standing is universally better than sitting.

Again, the useful part may be having another option.

Sit for a while.

Stand for a while.

Move when you can.

You don't need to spend your workday constantly thinking about your spine.

What can you realistically change during a busy workday?

This is where advice can get a little unrealistic.

"Just get up every 20 minutes!"

Great idea until you're in back-to-back Zoom calls from 10 until noon.

So start smaller.

If you're already getting up to make coffee, walk around for another minute.

Take one phone call standing.

Instead of sending your coworker a message, walk over if they're nearby.

Change your sitting position when you notice you're uncomfortable.

Go for a short walk at lunch when you can.

And if you enjoy exercising outside of work, keep doing that too.

Research specifically looking at office workers with lower back pain has found that workplace exercise programs can improve pain and other outcomes. Some of the programs included relatively short exercise sessions, which is a helpful reminder that movement doesn't always have to mean a full workout.

The best routine is probably the one that actually fits into your day.

Do you need to fix your posture?

Probably not in the dramatic way social media sometimes makes it sound.

There isn't one perfect posture that guarantees you'll never experience back pain.

That doesn't mean ergonomics are pointless.

If your monitor is so low that you're uncomfortable by noon, your chair doesn't support you comfortably, or your workstation makes you feel like you're fighting it all day, changing the setup may help.

But the goal isn't to create a position your spine must stay in.

It's to make your workspace comfortable enough that you can work and easy enough that you can change positions throughout the day.

Sometimes the simplest ergonomic advice is also the least exciting:

Make yourself comfortable and move sometimes.

What if you've changed your desk setup and your back still hurts?

This is when it can be useful to zoom out.

Maybe you've bought the chair.

Raised the monitor.

Added the lumbar cushion.

Started standing more.

And your back is still bothering you.

That's because back pain isn't always a desk problem.

An assessment can look beyond your chair and consider things like how you're moving, when symptoms appear, what your workday looks like, your activity outside of work, and what seems to make the discomfort better or worse.

For some people, chiropractic care may include assessment, hands-on treatment, exercise guidance, and advice around everyday movement.

Physiotherapy can also be useful when strengthening, mobility, or gradually building tolerance for certain activities is an important part of the picture.

At Hidden Valley Health Centre in NW Calgary, both chiropractic and physiotherapy are available, and care can be built around what you're actually experiencing rather than simply telling you to "fix your posture."

Your desk job isn't ruining your spine

If there's one thing to take away from this, let it be that.

You haven't failed because you slouched through your last meeting.

And you don't need to spend eight hours holding your shoulders back and your core tight.

Research gives us a much more flexible picture than that.

Sitting itself isn't necessarily the problem. But spending large parts of your day barely changing position may contribute to discomfort for some people.

So give your body a little variety when you can.

Stand up.

Take the long way to the kitchen.

Change positions.

Go for the lunchtime walk when your schedule allows it.

And if your back is still regularly reminding you that it's there, it may be worth looking at the bigger picture.

Because sometimes your body isn't asking you to find the perfect posture.

It just wants a few more chances to move.
